A pair of specific primers was designed based on the reported Bm86 gene of Boophilus microplus,the Bm86 gene was cloned by PCR using the plasmid pMD18-T-Bm86 as templates,and subcloned into the prokaryotic plasmid pGEX-4T-1.The recombined plasmid was transformed into E.coli BL21(DE3) and followed by expression of the protein induced by different concentration of IPTG for different time.SDS-PAGE showed that the recombinant plasmid pGEX-4T-1/Bm86 expressed a fusion protein Bm86-GST(Mr 94 000) after being induced with IPTG.High level expre-ssion of Bm86-GST was found at 1 mmol/L IPTG condition after incubation for 8 h at 37 ℃,and the expression level of the recom-binant Bm86-GST reached up to 29% of total E.coli proteins.Western-blotting analysis showed that the recombinant Bm86-GST was recognized by the rabbit anti-B.microplus positive serum.

Objective To discuss the surgery procedure and treatment effect of reconstruction of the soft tissue of the thumb/finger defects by the second toe tibial toe pulp skin flap. Methods Ten patients with the soft tissue of pulp of the thumb/finger defects were treat by the same side of the second toe tibial toe pulp skin flap, all the patients have the soft tissue defect of finger pulp with exposed phalanx. Crush them in 4 cases, the machine cut wound in 6 cases. A fixed 2 cases, delayed operation 3-7d after injury to repair in 8 patients. The side of skin flap varied from 2.0 cm × 2.2 cm to 2.0 cm × 3.5 cm. Results Ten fingers in 10 cases all survived. Necrosis in edge part of the shin graft occurred in 2 cases, which was healed through changing of dressing. All cases were followed form 4 months to 16 months. The blood-supply, texture and elasticity of transferred flaps and the shape of fingers pulp were excellent. Good function recovery of the fingers was achieved. Pain and temperature sence were regained. Two point discrimination of the finger pulp was 5-9 mm.Primary healing occurred in all cases. It did not disturb dressing shoes and walking. Conclusion It is a reliable approach for soft-tissue coverage of the thumb/finger using the second toe tibial toe pulp skin flap based on distal perforators of digital artery or ulnar artery. The advantages include simply procedures, reliable blood supply without sacrificing main aneries and possibilities of sensoly recovery.

Species identification using DNA sequences is the basis for DNA taxonomy. In this study, we sequenced the ribosomal large-subunit RNA gene sequences (3,037-3,061 bp) in length of 13 Chinese Theileria stocks that were infective to cattle and sheep. The complete 28S rRNA gene is relatively difficult to amplify and its conserved region is not important for phylogenetic study. Therefore, we selected the D2-D3 region from the complete 28S rRNA sequences for phylogenetic analysis. Our analyses of 28S rRNA gene sequences showed that the 28S rRNA was useful as a phylogenetic marker for analyzing the relationships among Theileria spp. in ruminants. In addition, the D2-D3 region was a short segment that could be used instead of the whole 28S rRNA sequence during the phylogenetic analysis of Theileria, and it may be an ideal DNA barcode.

Theileria annulata is a tick-borne intracellular protozoan parasite that causes tropical theileriosis, a fatal bovine lymphoproliferative disease. The parasite predominantly invades bovine B lymphocytes and macrophages and induces host cell transformation by a mechanism that is not fully comprehended. Analysis of signaling pathways by quantitative real-time PCR (qPCR) could be a highly efficient means to understand this transformation mechanism. However, accurate analysis of qPCR data relies on selection of appropriate reference genes for normalization, yet few papers on T. annulata contain evidence of reference gene validation. We therefore used the geNorm and NormFinder programs to evaluate the stability of 5 candidate reference genes; 18S rRNA, glyceraldehyde-3-phosphate dehydrogenase (GAPDH), ACTB (β-actin), PRKG1 (protein kinase cGMP-dependent, type I) and TATA box binding protein (TBP). The results showed that 18S rRNA was the reference gene most stably expressed in bovine PBMCs transformed and non-transformed with T. annulata, followed by GAPDH and TBP. While 18S rRNA and GAPDH were the best combination, these 2 genes were chosen as references to study signaling pathways involved in the transformation mechanism of T. annulata.

In order to determine the effect of various hosts on feeding performance of Rhipicephalus (Boophilus) microplus, we used 3 mammalian species as hosts, cattle (Qinchuan), sheep (T an), and rabbits (Japanese white rabbit) for infest-ing ticks. Five hundreds of R. microplus larvae were exposed to each animal (3 animals/host species). Tick recoveries were 11.0%, 0.47%, and 5.5% from cattle, sheep, and rabbits, respectively. The averages of tick feeding periods were not significantly different on cattle, sheep, and rabbits, 28.8, 25.3, and 26.7 days, respectively. The average weights of individual engorged female from cattle, sheep, and rabbits were 312.5, 219.1, and 130.2 mg, respectively and those of egg mass weights each to 85.0, 96.6, and 17.8 mg. The highest egg hatching rate was in the ticks from cattle (96.0%), fol-lowed by those from rabbits (83.0%) and sheep (19.2%). These data suggest that rabbits could be as an alternative host to cultivate R. microplus for evaluating vaccines and chemical and biological medicines against the tick in the laboratory, although the biological parameters of ticks were less than those from cattle.

In order to screen African swine fever virus (ASFV) diagnostic antigen with the best enzyme linked immunosorbent assay (ELISA) reactivity. By establishing the ELISA method, the diagnostic antigen of ASFV p30 protein expressed by baculovirus-insect cell expression system as reference, we explored the antigenic properties and diagnostic potential of ASFV p35 protein expressed by prokaryotic expression system as a diagnostic antigen. The results of Western blotting and immunofluorescence show that the molecular weight of the recombinant p35 protein and p30 protein obtained was 40 kDa and 30 kDa, respectively, and these two proteins had good immuno-reactivity with ASFV positive serum. Recombinant p30 and p35 proteins were used as diagnostic antigens to establish ELISA, and the sensitivity and repeatability of these methods were tested. The results show that although the detection sensitivity of the p30-ELISA established in this study was higher than that of the p35-ELISA, the sensitivity of p35-ELISA was 95.8%, and variations in intra- and inter-assay repeatability of the two methods were less than 10%. The coincidence rate between the p35-ELISA and the imported kit was 97.2%. Results show that p35-ELISA was sensitive and stable, and could detect specific antibodies against ASFV.
